In an improved procedure, chrysin (I) was alkylated with prenyl bromide (II) under phase-transfer conditions, and the resulting prenyl ether (III) was subsequently rearranged under microwave irradiation to produce a mixture of the title compound as the major product along with the 6-prenyl (VI) and the 6,8-diprenyl (VII) derivatives, which were separated by column chromatography.
